| Abstract [eng] |
The aim of the current work was to identify vibra-tional machine glass epoxy plate eigenfrequencies, numer-ically identify working regimes on different input parame-ters and investigate the blood flow in foot after vibrational excitation using high-sensitivity infrared thermal imaging camera. Novel training machine has been designed for this purpose. Two vibrating motors rotating on different revo-lution per minute value were used to induce beating phe-nomenon and create sufficient force. Comsol Multiphysics model was designed for eigenfrequency analysis of ma-chines’ vibrating glass epoxy plate. Natural frequency of 3.28 Hz has been observed on loaded beam. Experiments with training machine were executed with the purpose of identification of beating phenomenon induction regimes on vibrating frequencies close to calculated eigenfrequencies values. Motors supplied by 16.9 V and 13.9 V respectively created beating frequency of 3.311 Hz and generated force to legs of 180.2 N. After that foot temperature was regis-tered. Temperature raise of 0.7 C on Hallux toe, 1 C on Long toe, 0.9 C on right foot point and 1.5 C on left foot point were noted. |
